Argentina is now flush with street art. After dropping several solo pieces on the streets of Buenos Aires, Fintan Magee met up with Martin Ron to put up Castles In The Sand. Both artists are known for their hyper-realistic imagery, and this piece offers plenty of it. The mural depicts two young boys building a sand castle in a bright and colorful world that's contained within a bubble, a barrier that protects them from a drab and disparaging reality. A sea turtle appears to stand guard by the bubble, ensuring nothing punctures it too early.
